Can anyone help with:
What is the vertex for the function? (You will want to find the axis of symmetry first) Write as an ordered pair leaving no spaces, such as, (1,-4) y=-3x^2+6x ??

wolfe8 · Answer

You would differentiate that once and equate it to 0. Solve for x and substitute it back into the original equation for y.

anonymous · Answer

ok. 
How should I write that?

wolfe8 · Answer

Do you know how to differentiate equations?

anonymous · Answer

I'm sorry no.

wolfe8 · Answer

Ok do you want me to show you on a live whiteboard?

anonymous · Answer

Could you show here in replies

wolfe8 · Answer

Sure. Basically what you do is multiply the term with the power and reduce the power by one.

joannablackwelder · Answer

You can find the vertex without using calculus by putting the function in vertex form

joannablackwelder · Answer

y= a(x-h)^2+k where (h,k) are the coordinates of the vertex.

joannablackwelder · Answer

Do you know how to put your equaion in this form by completing the square?

joannablackwelder · Answer

*equation

anonymous · Answer

Well, I'm trying to figure that out. Sorry, but math is a struggle for me right now.

anonymous · Answer

I have to go tonight, I guess I will have to try to figure out the answer later on.

anonymous · Answer

Thank you.

joannablackwelder · Answer

Oh, ok. Good night!
